<p>We present a 3D object-space antialiasing technique for volume graphics. Our approach performs antialiasing once-on a 3D view-independent representation-as part of the modeling stage. Unlike antialiasing of 2D scan-converted graphics, where the main focus is on generating aesthetically pleasing displays, antialiasing of 3D voxelized graphics emphasizes the production of alias-free 3D models for various volume graphics manipulations, including but not limited to the generation of aesthetically pleasing displays.</p>
